We are experimenting with email templates to see if we can get the functionality that we currently have in Salesforce.

I have been able to add images to My Photos and then use the url as the image link in the email template.

The only issue with this is that we need to have a shared image library so that each person can create email templates using the same images. There does not seem to be a way to do this.

I have tried adding the images to the Company Drive and also to My Drive and giving any visitor read permission, but this only gives access to a download page, and the image does not appear in the email when received.

Is there a way of having a corporate/company images folder, or some way to enable access to images dynamically via a url, rather than via the download page?

Unfortunately this does not work as the link generated is for a page that lets you download the image, and is not a link to the image itself. This results in the image not being displayed in the email.
